6-8 hours is about dead right, although i'd say closer to 8. It all depends on traffic, and if there is construction on I-75 traffic may be a problem. Traffic going into atlanta is also quite bad, and the exists come up real fast so be sure and know where your goin first and not just count on road signs.
